On each visit I spotted several Common Blues flitting around the Bird's Foot Trefoil flowers almost immediately. After observing them for a while it became clear that the males were very flighty and not keen on me getting too close. They were also very territorial and would defend their patch from other males. The females on the other hand were not territorial and seemed happy to flutter randomly around a large area, and they also seemed much more tolerant of my presence.
A shot I was particularly keen to get was a reasonably wideangle image of a Common Blue in its natural setting with some blue sky in the background. Such as shot is not easy because the Tokina 35mm macro lens does require you to get very close to the subject, also I had to get down very low (I was actually lying on my stomach!). Also, the relatively wide angle of view means that lots of foliage inevitably gets into view and can look rather messy. Of course, the alternative would be to shoot in cooler conditions which might allow me to arrange the butterfly's perch in a more photogenic manner, but then of course I wouldn't get the blue sky. Basically, if the sun is out then these butterflies are on the wing and not amenable to being coaxed into position! Nature photography is all about trade-offs.
Anyway, after much perseverance and a great many shots that I wasn't happy with, I managed the shot below of a female Common Blue. Although it's not a classic macro (close-up) image, and perhaps not for everyone, I must admit I am pleased with this one. I like the colours, particularly the blue sky, I like the fact it is a female Common Blue as the females do tend to have the more attractive markings on the underside. And I like the fact it is an image of a butterfly very much in its natural environment.

To photograph one with its wings open showing the lovely blue colour I had to find a male which meant drawing upon the extra reach of my Sigma 150mm lens (this was before it broke - it is currently being fixed by Sigma by the way). The shot below was my favourite, and shows a male Common Blue in amongst the Bird's Foot Trefoil.
and secondly, a male on Bird's Foot Trefoil;
I suppose the moral of the story is that we have to tailor our photography to suit the conditions. Aim for images of butterflies with their wings open when the sun is out, but take a longer lens as you may not get close to them. If you can get close, then think about wideangle images with blue sky in the background. When it's cooler, butterflies are unlikely to have their wings open but will typically be more co-operative (and more difficult to find!).
